Hello,
I am trying to get my TT S2-3200 working on my Ubuntu 7.10 (original
Ubuntu kernel 2.6.22-14, and compiled 2.6.23.14 from sources).
I am using last sources from http://jusst.de/hg/multiproto
http://jusst.de/hg/multiproto/file/557067efd932/linux/drivers/media/dvb/ttpci/budget-ci.c
(multiproto-0659916f08b4).
But when a program like scan or szap2 tries to access the frontend, I
get the kernel oops I have attached to this message (tt-s2-3200-oops.txt
for an smp kernel and tt-s2-3200-oops-nosmp.txt for a no-smp kernel)
Am I wrong somewhere ?
